Affordable Tire Company

I went to Affordable Tire to see if they could swap tires out as I have a brand new tire that is different size then what's on my car. It's a brand new tire and they tried to tell me that the bead was broken inside even though it's brand new and was taken off the rim by a tire shop. After the manager looked at all the tires on the vehicle he tried to tell me that one of my front tires was worse and showing cords and that I should put it in the back and get the back one fixed first and put that new tire on the front. I asked the manager why I would put that tire on the back and how is it showing cords as it was just replaced by them. The manager didn't have a answer. I told the manager I had receipts that I purchased that tire from them and he told me they wouldn't replace it if it was longer than 30 days even though it states on there paper work they guarantee there work and stand behind there work. I will never go there again and will not refer anyone to them. They have bad customer service and don't stand behind there work.
